Description

The present invention relates to a dispensing device, and more particularly to a dispensing device having a dispensing stand through which a dispensed beverage is guided in use. Such a dispensing device is known from EP 0 224 293.

BACKGROUND OF THE INVENTION

This known dispensing device comprises a refrigerator in which a number of beverage container containers are placed. On the refrigerator there is a hollow tapping stand through which the tapping pipe passes. This tapping line is connected to the back of a known tapping tap which is mounted on the tapping stand so that the beverage can be expelled from the container to the tapping tap by, for example, CO ₂ gas being introduced into the container. The hollow dispenser is in a free permeable connection with the interior of the refrigerator, so that relatively cool air can in principle flow from the refrigerator to the dispenser, in which the cold air can surround the dispensing duct. In use, this equipment leads to cooling of the tapping line and the beverage flowing through the tapping line.

This known dispensing device has the disadvantage that the air in the dispenser will not substantially move. The cold air will actually heat up and as a result will rise upward in the dispenser rack, since warmer air is relatively light with respect to the cold air present in the refrigerator. A relatively small opening is provided in the dispenser proximate to the tap piping through which some air may escape. This improves the movement of the air in the dispenser, but causes problems in the vicinity of the dispenser to cause undesired flow of cold air precisely in the direction of the dispenser and of the person controlling the dispensing tap, while also losing more energy because leaking relatively cold the air in the refrigerator is replaced by relatively warm air that is drawn in from the surrounding environment and must be cooled, for example, from room temperature to a temperature in the range, for example, of 4 to 6 degrees Celsius.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a dispensing device of the kind described in the introduction, wherein in this improved dispensing device the disadvantages mentioned are overcome, but the existing advantages are retained. In this sense, the dispensing device of the present invention is characterized by the features defined in claim 1.

In the dispensing device of the present invention, the two channels that are in transit interconnect form a continuous passageway for conveying the coolant. Since the tapping line is guided in one of the channels, namely the other channel, cooling of the tapping line will be performed in the respective channel. That is, during use, the beverage that flows through the stub line from the container to the stub will be effectively cooled. Because circulation of the cooling medium in the interconnection of the first and second ducts is possible, this technical equipment will simply prevent unwanted leakage of the cooling medium in a disadvantageous amount, at least through a tap.

In an alternative embodiment, the dispensing device according to the present invention is further characterized on the basis of the features defined in claim 2.

In contrast to the known dispensing device, the cooling medium will be repeatedly circulated so that a cooling flow of the cooling medium, namely air, can be created. In addition, there will be essentially no loss of coolant at least through the tap. This will minimize or completely obstruct the user's control of the dispensing device.

By incorporating the guide tube into the dispensing rack, a first channel is formed between the dispensing rack and the guiding tube, which is at least proximate the dispensing pipeline in interconnection with the second channel formed by the guiding tube or at least in the guiding tube. Under the conditions of use, a resultant flow can be achieved in the guide tube and the channel formed, as a result of which the coolant piping in the guide tube is blown with coolant. Due to the possibility of the passage of a cooling medium, namely air, between the first and second ducts, forced cooling of the tapping duct through which the beverage flows flows is achieved.

Advantageously, the dispensing device comprises pressure means for forcing a coolant flow in the channels. In this case, the flow is not solely dependent on natural phenomena. These pressure transducers can perform their function by providing an inlet pressure in the inlet port to the first or second passage, but in use it is advantageous to create a vacuum in the passage outlet located in the specified flow direction, which causes the refrigerant to be sucked into the passages . This is particularly advantageous because, in the case of small leaks in each of the channels, air is sucked only from the surroundings, thus preventing the coolant from escaping into the environment, thereby further reducing the obstacles which make the user of the dispensing device uncomfortable.

In a particularly preferred embodiment, the dispensing device of the present invention is further characterized by the features defined in claim 5.

The use of air that is cooled in the refrigerator provides the advantage that the required temperature is achieved in a relatively simple manner. What is achieved in a relatively simple manner is the generation of considerable temperature differences between the temperature of the tapping line or at least around the tapping line in the refrigerator and in the tapping stand. It is then preferred that the cooled air first flows through the second passage and is discharged back from the tap through the first passage towards the refrigerator. Advantageously, subsequently, the air from the refrigerator is recirculated through the channels and is returned to the refrigerator, for example, via an evaporator or other refrigerant cooling means which resets the air temperature. This is particularly advantageous from an energy point of view, since relatively little energy is required to cool the air, which is slightly heated in the dispenser rack. Furthermore, the use of air provides the advantage that any leakage of coolant into the environment will not lead to harmful contamination, so that there is no need for any particularly complicated sealing.

In a particularly preferred embodiment, the dispensing device of the present invention is further characterized on the basis of the features defined in claim 7.

As mentioned above, a vacuum effect is used to generate current in the channels. Applying a vacuum chamber in fluid communication with the first passage provides the advantage that the vacuum chamber will suck air or at least coolant from the first passage, i.e., the effect of equalizing the pressure difference will suck air into the second passage. As a result of the connection of the second air channel to the interior of the refrigerator, the flow of, for example, air from the refrigerator into the vacuum chamber will be forced. Under conditions of use, the vacuum chamber will generate a lower pressure than ambient pressure by means of, for example, a ventilator that expels air from the vacuum chamber back to the refrigerator to cool the containers that are in the refrigerator and to circulate again. of air in the channels.

It seems advantageous if the first duct is in interconnection with the second duct within the tap. Under the conditions of ingestion, cooling can be carried out in this way over the greatest length of the tapping line. Advantageously, the stub stand and optionally the guide tubes have thermal insulation, which is achieved, for example, by providing a heat-insulating layer. In this way, undesired cold perception when touched on the stub stand and undesirable heating of the cooling medium flowing in the first passage by the effect of heat in the surrounding environment are suppressed in use. The thermal insulation of the guide tube thus provides the advantage that the heat exchange between the cooling medium flowing in the first and second ducts is limited, which advantageously contributes to the cooling of the stub pipe.

In a further preferred embodiment, the dispensing device according to the present invention is further characterized on the basis of the features defined in claim 11.

The design of the stub line as at least partially flexible tubing, which is adapted to be connected to the stub cock, provides the advantage that adaptation of the stub line is readily feasible. In fact, this tubing can easily be passed through the guide tube, for example, into the open end, which is further from the tap, up to the location of the tap, where the tubing can be connected to the tap. This allows for easy replacement of the stub piping, for example, each time a new container container is encountered. The cartridge containers are preferably ingested with a flexible dispensing piping connected thereto and supplied with the dispensing container, wherein the dispensing pipeline is temporarily introduced into the guide tube and connected to the dispensing tap so that the beverage can be pumped from the dispensing container through the dispensing tap. whereas, while removing the container, the tapping line is disconnected from the tap and removed together with the container. As a result, the cleaning of the stub piping is no longer necessary, thus avoiding pollution of the environment more easily. This is particularly advantageous when the container containers are located relatively close to the tap cock, such as when the container containers are relatively close to the tap cock, for example, in a refrigerator which is located below the tap connected to the dispenser rack.

In the dispensing device according to the present invention, the dispensing tap can be designed such that, together with at least the flexible portion of the dispensing pipeline, it can form a tubing cock, so that due to elastic deformation this dispensing portion can be drawn to the dispensing tap and re-openable tap cock controls. However, it is preferred that a valve is incorporated into the tapping line which can be actuated by means of the tapping tap to reach an open and closed position. In the embodiment just described, the advantage is achieved that the tap cock cannot come into contact with the dispensed beverage, which makes it impossible to contaminate the tap cock with the beverage and, moreover, to contaminate the beverage due to contact with the tap cock.

In a particularly preferred embodiment, the dispensing device according to the present invention is further characterized by the features defined in claim 18.

In such a dispensing device, the rack and guide tubes pass through the dispensing table on which the dispensing rack and guide tubes are disposed and through the wall of the refrigerator, thereby providing an easy, direct connection between the dispensing plate and the refrigerator. The distance between the refrigerator and the tap is thus reduced to a minimum, hence the need for relatively short channels. In addition, a relatively small length of the guide tube is required, which is particularly advantageous when the at least partially flexible tube is to be drawn through a predetermined channel from the interior of the refrigerator to or near the tap cock. This means that the stretching of the stub pipe is further simplified. Advantageously, the guide tube is rigidly connected to the drill stand, the guide tube extending through the vacuum chamber and being attached to the lower side of the vacuum chamber in a situation where the drill stand is also mounted. For this purpose, for example, a screw thread can be provided on the guide tube, on which the nut can be rotated as the guide tube is attracted to the vacuum chamber. A screw thread can also be formed in the vacuum chamber, which has the ability to cooperate with the thread on the guide tube when tightening. These possibilities will be readily apparent to the skilled artisan.

At least two delimited positions for the container containers are formed in the refrigerator used for the stowing device according to the present invention, with separating means having thermal insulation properties placed between these delimited positions or at least between the container containers. In particular, such separating means provide for the isolated separation of an already cooled container from, for example, a relatively warm container which has been placed in the refrigerator at a certain time interval and is intended to be cooled for later use. This makes it impossible to heat the already cooled container from another, relatively warm, container. In addition, it is achieved that the air flowing in the channels is air that comes from the vicinity of the already cooled container. The separating means may be fixedly installed inside the refrigerator, or may be partially connected to its door.

The dispensing device of the present invention may be further characterized by the features defined in claim 21.

Such a dispensing device provides for the possibility of regularly replacing the dispensing piping, which is preferably carried out jointly by each container that is consumed therein. This means that the stub piping does not have to be further cleaned in principle, but can be installed and removed together with the container. In this case, each time a new or at least another storage container is used, the tapping line is changed, which makes it impossible to mix the beverages and there is always a clean line that is particularly hygienic. In addition, cleaning costs are saved. However, if such an intention exists, then such a tapping line may be cleaned, but this cleaning takes place at a distance from the tapping device, so that the tapping device must only be out of operation for a minimum period of time during the exchange of the container and the tapping pipe. This is particularly advantageous when relatively small kegs are used as container containers having, for example, 10, 20 or 30 liters capacity. The first end of the stub pipe, which is in a guiding position when introduced, may be connected to the stub cock, while the distal second end serves to establish a connection with the container. To this end, the other end may be adapted to be connected to the container by, for example, using a quick coupling means, but it is preferred that the stub pipe is firmly connected to the container so that it cannot be detached without damage. This further ensures the hygiene aspect of the present invention. During the introduction of the stub pipe into the guide tube of the stub device according to the present invention, the leading first end is covered by means of a cap cap with a rounded tip. This ensures protection of the open, guiding end of the stub pipe itself against the ingress of dirt, which is particularly important because during insertion this end will pass through the inner part of the guide tube, in which, for example, it may be one or more bent. The rounded top of the cover cap provides the advantage that it substantially improves the insertion of the stub pipe, resulting in a particularly easy extension of the stub pipe. As a result, the dispensing device according to the invention continues to be improved in terms of hygiene and ergonomics.

The present invention further relates to a method of assembling a dispensing device according to the steps defined in the form of the measures set forth in claim 26.

Using this method, a dispensing device can be assembled in an easy manner in which, at least during use of the dispensing pipe, it is guided in the guide tube up to the dispensing tap, the dispensing pipe being surrounded by a passage channel in the dispensing pipe. This channel can be connected to another channel that runs between the guide tube and the wall stand dispensation so that the coolant may flow in both channels and thus to cool at least the greater part of a tapping pipe. In this specification, a gaseous refrigerant, namely air, is disclosed as a useful refrigerant. It will be understood, however, that other coolants may also be used, such as coolants, which may also be water. For the reasons mentioned above, the use of air is preferred.

In the method according to the present invention, the dispenser rack can be attached directly to the refrigerator, for example on its top surface which forms the dispenser table. However, it appears advantageous that the tapping stand is mounted on the tapping table so that at least the guide tube passes through the tapping table and the wall, namely the top wall of the refrigerator which is located below the tapping table, thereby creating a through connection between the interior of the refrigerator and the interior of the guide tube. Then, it is particularly preferred that the dispenser also extends at least through the wall of the refrigerator, while a chamber is formed inside the wall which is in fluid communication with the channel between the guide tube and the dispenser, but separated from the interior of the guide tube. Such a chamber may be designed to be a vacuum chamber, by means of which air is sucked from the interior of the refrigerator and flows through both channels into the vacuum chamber and can be discharged therefrom into the cooling means.

It will be appreciated that the flow of coolant in the channels may be generated using another method, such as placing special air cooling means between the two channels and a duct duct that connects to a storage container located at a greater distance and which is preferably thermally insulated where this stub line is not surrounded by a guide tube.

The present invention further relates to a method for producing a dispenser according to the steps defined in the form of the measures set forth in claim 32.

Using this method, a dispenser rack which is particularly advantageous for use with the apparatus or method of the present invention can be manufactured relatively simply. By using the guide tube as an insert which is embedded in the pin stand, there is the possibility of easily forming the guide tube in the desired shape without the need for additional installation. This leads to considerably greater freedom in assembling the design of both the guide tube and the dowel while substantially reducing the number of adjustments.

The present invention further relates to a beverage container which is characterized by the features defined in claim 34.

Such a container is particularly suitable for use in a dispensing device and method according to the present invention, since the at least partially flexible hose makes it particularly easy to install and remove the dispensing pipe. The primary valve then prevents the beverage from flowing into the dispensing pipe before use. This means requiring less stringent requirements for the damming properties of the tappings. In addition, the stub tube may have an open end. Advantageously, a valve, which, as mentioned above, can be connected to a tap for mutual cooperation and which can open or close the throughput of the tapping pipe, is placed in or onto the tapping hose. This simply prevents the beverage from escaping. In the case of such a configuration, the primary valve may at least be omitted at least between the container and the stub pipe. However, even in this embodiment, it is preferred to use a primary valve in order to further prevent the oxidation of the beverage.

Other advantageous embodiments of the dispensing device, method and cartridge container of the present invention will be defined in more detail in the other dependent claims.

DETAILED DESCRIPTION OF THE INVENTION

Throughout this specification, the same or corresponding parts are designated by the same or corresponding reference numerals. At least with respect to the tap cock and the tap cock cooperating with the valve body or shut-off valve, a reference is made to the applicant's Dutch patent application entitled "Beverage dispensing assembly and container for carbonated beverage and beverage dispensing piping for use in such an assembly" on the same date and which the applicant considers to be an included link. In addition, with respect to container containers that are useful in the apparatus of the present invention, reference is made to International Patent Application PCT / NL99 / 00454, filed by the same Applicant and incorporated herein by reference.

In FIG. 1 is a perspective view with a partial cut-out showing a tapping device 1 according to the present invention. The dispensing device 1 comprises a dispensing table 2, such as a bar counter, with a refrigerator 4 located below it and in which a storage container 6, such as the container shown in FIG. 10 is shown in dotted lines. On the table 2 there is placed a stand 8 which is fixed in the manner shown in FIG. 2. The tapping stand 8 has a first end 10 which rests on the tapping table 2, while a tap tap 14 is mounted at the opposite, second end 12. Such tap tap is shown in more detail in FIG. 8 and its description can be found in said Dutch patent application. In FIG. 3, a guide tube 16 having a first end 18 which is located near the second end 12 of the dispenser 8, while the second end 20 of the guide tube 16 extends beyond the first end 10 of the dispenser 8 into the interior 22 of the refrigerator 4. Inside the first end 10 of the dispenser stand 8 is formed a threaded hole 24 into which a mounting sleeve (not shown) is screwed, on which an external thread is formed. This fastening sleeve 26 extends through an opening 28 in the docking table 2. The fastening nut 30 is pulled on the fastening sleeve 26 to the underside of the dowel table 2 so that the dowel stand 8 is firmly attached to the dowel table 2. 30, enters the aperture 32 in the top 34 of the refrigerator 4. The vacuum chamber 36, which will be described in more detail below, is secured by screwing the flange 38 into the aperture 32 at the lower end of the mounting sleeve 26 to form a rigid connection between the refrigerator 4, The guide tube 16 passes with some play the inside of the fixing sleeve 26 and then through the bottom 40 of the vacuum chamber into the interior 22 of the refrigerator 4.

In the embodiment just described, a pipe 42 is inserted into the second end 20 of the guide tube 16, which enters the front of the interior 22 of the refrigerator 4 at least as far as to reach the door 44 of the refrigerator 4. At the distal end of the introduced tube 42 from the guide tube 16, there is a funnel-shaped insertion member 46 which is open to the interior 22. It is preferable that the design of the stub stand 8 and / or the guide tube 16 exhibits thermal insulation properties, for example by applying a lining or using heat insulating material. manufacturing a tapping stand 8 and / or guide tube 16.

In the conditions of use, the stub tube 48 extends from the interior 22 through the guide tubes 16 and the insertion tube 42 to a location beyond the first end 18 of the stub tube 16. This stub tube 48 may be rigidly mounted in the stub frame 8, but so that the stub tube 48 can be at least partially bent with respect to its introduction through the guide tube 16 and subsequent extraction in the manner described below. In the conditions of use, the first passage 50 is formed between the guide tube 16 and the wall of the dispenser rack 8 and the second passage 52 is formed between the wall of the guide tube 16 and the dispenser line 48. In the situation where the dispense tap is installed, That is, under conditions of use, fluid, namely air cooled in the refrigerator 4, can flow through the insertion member 26 along the stub pipe 42 led in the second duct 52 and from there through the interior space of the stork. The coolant, in particular the cold air, then flows into the interior of the vacuum chamber 36 from where it can flow through the outlet duct 54. It will be clear that the air that is being cooled in this way flows from the internal space 22 into the second channel 52 and a first duct 50, blowing off a portion of the stub pipe 48 contained in said second duct 52 and cooling the beverage that flows through this section of the stub pipe 48. In FIG. 10 it is schematically shown that cooled air is then discharged through the vacuum chamber 36 and the outlet duct 54 into the cooling means 56 of the refrigerator 4 and subsequently introduced into the interior 22 of the refrigerator 4. Apertures may be formed near the upper, first end 18 of the guide tube 16. 19, by means of which it is possible to create a substantially intense flow, thereby improving the cooling operation. Also, the contact surface of the stub pipe 48 can be increased, for example, by applying ripples or the like.

On the side of the cock 14, which is closer to the tap stand 8, a conical wall 61 is formed which simplifies the insertion of the tap pipe 48 and moreover provides a better connection between the two channels 50, 52. In this context, the wall 61 can also be positioned even higher Thus, the guide tube 16 can be introduced into the tap 14 up to a point near the wall 61, so that a portion of the stub pipe 48 located in the tap 14 is also cooled.

A valve assembly 60 is provided at the first end 58 of the stub tube 48 and has the capability of cooperating with the stub cock 14 as shown in FIG. 8 and further described in the applicant's Dutch patent application, which has already been mentioned above and is entitled "Beverage dispensing assembly and container for carbonated beverage and beverage dispensing piping for use in such an assembly". As can be clearly seen from FIG. 8, the valve assembly includes a spout 64 operatively extending outwardly of the tap cock body 62, wherein said spout 64 is secured to the tap cock body 62 by means of a protrusion 66 that engages a circumferential groove 68 in the spout 64. After mounting the spout In the sleeve 64, the tap cock body 62 is substantially completely airtight. Therefore, the air flowing from the first passageway 50 will not be able to exit from the tap cock body 62 otherwise than through the second passageway 52 and along the tappings 48. On the side located in the tap cock body 62, a spout 64 is provided a movable body which is actuated by the actuation mechanism of the tap cock 14 so that the body 70 can be moved in a straight line with respect to the spout 64 between a first position in which the beverage can be discharged through the spout 48 and the spout 64 and a second position shown in FIG. . 8, in which the outflow nozzle 64 is separated from the stub pipe 48, thus discharging the beverage is not possible. Because the spout 64 extends from the tap cock body 62, the tap cock body 62 does not come into contact with the beverage. The tap cock body 62 has a divisible structural structure so that in the divisible position the tappet 48, namely the outlet nozzle 64 or at least the valve assembly 60, may be incorporated into the tap cock 14 or removed while the tap cock body 62 is When closed, the actuation mechanism of the tap cock 14 can control the release of the flow connection between the tap pipe 48 and the outlet nozzle 64.

In FIG. 2 is a cross-sectional side view schematically of how a cooled stub pipe 48 with its guide end 48 can be introduced into a guide tube 16. The discharge nozzle 64 is covered with a cap cap 72 having a rounded top 74 which prevents the at least 72 cover from jamming. The parameters of the length of the cover cap 72, the valve assembly 60, and the flexibility of the stub tube 48 are adapted to the bends of the stub tube 16 so that the stub tube 48 can be completely introduced through the stub tube 16 to the position shown in FIG. 3. The guide tube 16 is designed to have a wide oval bend as shown in FIG. 4, so that the longitudinal axis of said cross-section is in the plane in which the respective bend is located, thereby providing more insertion space while maintaining approximately the same passage area of the first duct 50 and the second duct 52. In addition, this construction results in that a more advantageous coolant flow ratio is achieved in the bends. During the introduction of the stub line, the cap 72 functions to seal the open end of the spout 64, thereby preventing contamination of the spout 64. The valve 60 is preferably designed to remain closed when pressure is applied to the cover cap 72 in the direction of insertion of the stub pipe 48. This design makes it impossible to open the valve 60 during the introduction of the stub pipe 48.

As can be seen in FIG. 9, in a preferred embodiment it is possible to place two container containers side by side in the interior 22 of the refrigerator 4, one of which may be impacted while the other may be cooled. In FIG. 6, the storage container 6 drawn on the first side is encountered. That is, the stub pipe 48 is connected via the stub head 76 to the primary shut-off valve 78 of the storage container 6. This primary shut-off valve 78 ensures complete closure of the storage container and can only be opened by the means of the staple 76. a supply conduit 80 which is connected to a pressure source, such as a CO ₂ compressed cylinder, which is commonly used in dispensing devices and shown in FIG. 12. However, the container 6 may be constructed, for example, as described in the aforementioned International Patent Applications PCT / NL99 / 00454 or PCT / NL99 / 00144, which the Applicant considers to be incorporated by reference. In particular, in the case of the use of a pouch in a container or a pouch in a box as a container 6, as described for example in PCT / NL / 00454, the device according to the invention can also be used in connection with beverages not carbonated and which include juices, dairy drinks and pre-mixed or post-mixed non-alcoholic beverages. By connecting the primary valve 78 to the stub head 76, the possibility of conveying the beverage from the cartridge container 6 through the stub pipe 48 to the stub cock 14 is created. In the embodiment just described, a corresponding shaping is formed on the rear wall 82 and the door 44. in fact, they touch each other between the two container containers 6, so that the container containers 6 are at least to some extent thermally insulated from each other. Other means which are useful for forming thermal insulation may also be used for this purpose.

Especially from FIG. 1, 10 and 13, it can be seen that in the rear wall 82 of the refrigerator 4 there is a space 86 in which the cooling means 56A is located, as well as a fan 86 which in use directs the cooling medium flow into the opening 88 connecting the space 86 with the interior 22. In the space 84, the conduit 54 terminates and its outlet is preferably located near or within the cooling means 56A. Thus, in operation, the fan 86 will expel air from space 84 to interior 22, resulting in suction of air from vacuum chamber 36 via outlet conduit 54 and creating vacuum in vacuum chamber 36. The effect of this vacuum will be to evacuate air from the first passage 50 resulting in is that the air flowing through the tap cock is sucked out of the second duct 52. Since both ducts 50, 52 and the tap cock 14 are designed to be airtight during use, the air that will be sucked It is preferable that the outlet duct 54 is sized so that the outgoing air can only flow to the fan through the cooling means 56A and therefore the air that enters the interior 22 is cooled to the desired temperature. for example in the range of 0 ° C to 6 ° C. In this way the air circulates repeatedly and its temperature is kept at a relatively low level, so that condensation is at least largely prevented.

In the embodiment shown in FIG. 10, an evaporator 92 is disposed below the lower plate 90 of the refrigerator 4. The refrigerator 4 is located below the dispensing table 2 so that air can be sucked through the top and rear of the refrigerator 4 and can be discharged around the evaporator 92 below the refrigerator 4 as schematically shown. FIG. It is preferred that the bottom 90 is designed to open when cleaning the evaporator 92. However, it will be clear that other types of cooling mechanisms known in the art may also be employed.

The dispensing device 1 of the present invention may be assembled in accordance with the following procedure. A suitable position for placing the dispenser rack 8 on the dispensing table 2 is selected, for example, depending on the position of the dispensing grid 9 or the wash sink. Then, a hole 28 is drilled at a designated location on the drip table 2. The refrigerator 4 is placed in a suitable position below the drip table 2 and a drill hole 32 is drilled at the top 34 of the refrigerator to subsequently match the hole 28. the sleeve 26 and after its insertion into the hole 32, a fastening nut 30 is screwed onto the mounting sleeve 26 between the top 34 and the pin table 2. The first end 10 of the pin stand is screwed onto the upper end of the mounting sleeve 26 so that the pin table 2 is clamped between said first. This results in the formation of a firm connection between the dispensing table 2 and the refrigerator 4. Naturally, another applicable assembly procedure can be used at its own discretion. The insertion tube 42 can be brought to a position where the insertion member 46 is in a suitable position with respect to the door 44, for example by the rotation of the vacuum chamber 36, for example in the middle of the refrigerator 4 when viewed at least from the front. In such a case, it is preferred to use an outlet conduit 54 having at least a partially resilient structural structure to be introduced into the space 84 at any position of the vacuum chamber 36. The tap cock 14 is screwed to the end 12 of the tappet rack 8.

The container 6 with the connected or at least attachable stub piping 46 may be placed in front on the bottom 98 of the interior 22. The bottom 98 has a cross-sectional shape which allows the interior of the container 6 to be positioned upright as in the upright position. Fig. 10 as shown in broken lines or in a slightly inclined position as in FIG. 10 is shown in solid lines when the primary valve 78 is in front of the refrigerator 4 and is easily accessible when there is a need to manipulate the stub head 76. Under these circumstances, the center of gravity position Z provides certainty that the container 6 will remain stationary. The stub pipe 48, with its guide top 74, is inserted into the insertion member 46, passes through the guide tube 16 while the stub cock 14 reaches the split position. The stub pipe 48 is then inserted into the stub cock 14 after the valve 60, after which the cover cap 72 can be removed and the stub 14 can be closed. The optionally inclined container 6 can then be straightened to a vertical position and the refrigerator closed, and the dispensing device 1 is then ready for use. The operation of the dispensing tap 14 will then control the dispensing of the beverage that is discharged from the container 6.

After the container 6 has been emptied to a specified level, another container can be encountered. For this purpose, the primary dispensing head can be moved to the new container 6, but it is preferable to remove the entire dispensing pipe 48 and install a new dispensing pipe with a shut-off valve 60. At this stage the dispensing tap 14 can be split and the dispensing pipe 48 can be pulled out. into the inner space 22, or if the stub line 48 is disconnected from the stub head 76, the stub line 48 can be completely pulled out of the guide tube 16 through the stub cock 14 over its entire length. Replacing the stub tube 48 provides the advantage that they create better hygiene conditions and make it impossible to mix drinks. If the stub tube 48 in the device 1 is relatively fixed in the guide tube 16, it may also be rigidly connected to the tap 14 so that at each replacement the stub head 76 may be connected to a new container 6 after prior cleaning, which is carried out as needed. in a manner known per se.

The guide tube of the present invention may be constructed of plastic such that it is fully or partially resilient, for example, as schematically shown in FIG. 6. Such a guide tube may be incorporated, for example, into a metal bolt stand 8, such a bolt stand being, for example, an already existing type of bolt stand. In this patent application, a dispenser, often referred to as a pedestal, a beer machine, a dispenser, and the like, is to be construed to designate at least the portion of the dispenser that is disposed on the dispenser table. In the embodiment just described, the guide tube 16 has the shape of an arc 92 and a relatively rigid structural structure, which has a flattened cross-sectional shape, oval, and is designed to direct its ridges outwardly. The inwardly directed, circumferentially extending grooves 98 have a height H that is substantially less than the curvature of the top 74 of the cap 72, which provides an even better possibility of preventing the top 74 from jamming in the resilient portion 94 during insertion of the stub tube 48. It is made in the form of a slightly expanding, funnel-shaped shape, so that insertion of the top 74 is readily feasible. In such an embodiment, the guide tube 16 can be guided, for example, from the other end 12 of the dispenser rack 8, until the arc 92 has reached a predetermined position.

In the alternative embodiment shown in FIG. 7, a relatively rigid, for example, metal guide tube 16 having a spacer ring 17 is inserted into the forming die 100, from which FIG. 7 only one half. A removable core is formed around the guide tube 16 in the form of a first channel 5, followed by casting of the pin rack 8 around said guide tube 16 using a metallic material such as stainless steel, aluminum or the like. Then, said core (not shown), which is made, for example, of sand or wax, is removed until it has disappeared during casting, so that the result of the described process is to obtain a finished, one-piece stub stand 8 with guide tube 16. In this embodiment In addition, the ring 17 can be used in the installation of the fastening sleeve 26, which for this purpose can also be cast as part of a single molded unit.

In an alternative embodiment, the rod 8 is made of two or more parts such that the individual parts can be assembled around the guide tube 16 or the middle wall to separate the channels 50, 52. The guide tube 16 can also be made of two or more parts and for example by sliding the individual parts into the dispensing rack from opposite ends. In this case, a sealing ring such as a fusible ring may be used to join the parts together.

In FIG. 12 shows an alternative embodiment of the device 1 according to the present invention, in which the dispenser rack 8 is mounted in a conventional manner or as described above on the dispenser plate 2 and has at least one passage formed, for example, by the guide tube 16 described above or hole in the docking stand. An insertion tube 42 with an insertion member 46 is connected to this passage so that the stub tube 42 extends from the bottom of the stub table 2 through the insertion tube 42 and the stub stand 8 to the tap 14, resulting in the installation of the outlet end 64 in the same manner as in the previous text. Advantageously, downstream of the guide spout 64 is the valve 60 described above. Advantageously, downstream of the guide outlet end 64 is a valve 60 having the ability to cooperate with the actuating mechanism of, for example, a tap, as described above. However, the tap cock 14 may have a structure that allows the tappings 48 to be compressed and closed or opened near the outlet end 64 so that the tap tap 14 together with the tappings 48 form a hose tap. In contrast to the embodiment described above, in the embodiment just described, the outlet end 64 preferably has a rigid structure to facilitate positioning of the outlet end 64 and of the stub. In fact, the outlet end 64 may be part of a single unit of the tap cock 14 into which the end 58 of the tappet 48 is inserted.

In the embodiment shown in FIG. 12, the tappings 48 are connected to the container 6, which is located at a distance from the table 2, via a pin head 76. For example, the container 6 may be, together with the CO ₂ cylinder 81, another comparable pressure source that connects to said container. The container can be placed in a cellar or the like via an inlet conduit 80, or it can be placed freely under the faucet, which is the outside of the refrigerator or the like. Optionally, the insertion tube may extend to the proximal head 76. If the insertion tube 42 is of considerable length, mechanical means such as hand or electrically operated insertion rollers or the like may be used to facilitate insertion of the stub tube 48. As shown in this embodiment, a cooling device 45 is disposed adjacent to the dispensing rack 8, for example, located between the insertion tube 42 and the insertion member 46, to cool the dispensing pipe 48. Using such a refrigeration apparatus, the beverage is discharged from the dispenser. The storage container 6, which is preferably placed in a relatively cool location, can be further cooled to the desired temperature. Especially in the case of a drink that is consumed at a relatively high temperature, such as a temperature in the range of 10 ° C to room temperature, the use of such a device is particularly suitable. Using suitable cooling means 45, the beverages can be consumed at a lower temperature.

In FIG. 13 shows a further alternative embodiment of the dispensing device according to the present device, which substantially corresponds to the dispensing device described above with reference to FIG. 1 and 10. In this embodiment, in which some reference numerals have the same numeric designation, an air conduit 55 having a first end located in or near the fan 86 and an opposite end that is in a transient design with the insertion tube 42 is used. and at least with the first passage 50. Preferably, near the insertion member 46, there is a constriction 47 in this insertion tube 42 which relatively closely surrounds the tappings 48. This constriction may optionally be slightly resilient so that the leading end of the tappings 48 with valve assembly will be able to move through the constriction 47 due to elastic deformation, but at the same time the constriction 47 abuts the duct 48. After the fan 86 is started, air will be expelled through the air duct 55 into the first duct 50, while the constriction 47 will largely prevent cold air22. In this embodiment, the exhaust duct 56 will extend to below the coolant means 56A so that air passing through the exhaust duct 54 will only be able to move through the coolant means 56A to the fan 86 and the air duct 55. generating less vacuum under the cooling means 56A so that air will be sucked in front of the exhaust duct 54. Another option permits the application of a second fan, for example, near the lower end of the exhaust duct 54 or vacuum chamber 36, or between the two components, or at least a better controllable suction operation. In this case, in an alternative embodiment, the fan may be omitted.

Surprisingly, it has been found that due to the control of the pressure in the cans 50, 52, the desired cooling can in any case be achieved. If excess pressure is set in the first passage 50, then an overpressure is similarly created in the faucet 14, and therefore the stub pipe 48 and valve means 60 will also cool in the faucet 14. By generating a slight pressure drop in the second passage 52 at least with respect to the pressure in the first passage 50 ensures proper air circulation and thus does not expel an unintentionally large amount of cold air through at least the tap 14. Then, it is preferable not to select too much vacuum to prevent large amounts of warm air from being drawn through the tap. With this in mind, an energy-efficient tapping system is created. The desired pressure distribution can be achieved using both a single fan and more than one fan.

In the embodiment just described, an insertion passage 42 is provided below the pressure chamber 36 with two opposite branches 57 to which the air supply line 55 can be connected. In each case, one branch 57 is used, while the opposite branch 57 is closed by a cap or the like. This construction provides the advantage that the tapping stand 8 can be placed in any desired position on the top of the refrigerator while the air duct 55 is always connected in the necessary manner. The vacuum chamber 36 used herein has a rotatable structure.

The dispensing device of the present invention may be installed permanently or may be movable, for example, on wheels. Surprisingly, it has been found that a dispensing device according to the present invention can have the effect of attracting customer interest. Especially when the dispensing device according to the invention is used in a relatively hot environment, the condensation accompanying features of the dispensing stand 8 are present, thereby achieving an attractive cold appearance. This results in increased sales turnover. The cooling means of the dispensing device according to the present invention are preferably adjusted so as to prevent the formation of ice while achieving maximum cooling effect.

It will be appreciated that in the case of the device of the present invention, the stub pipe 48 will be depreciated together with the container 6 and, after use and cleaning, the valve 60 will be reusable under circumstances. Impairment together with the reservoir provides the advantage of improved hygiene, especially when the outflow end 64 is also present in the spoiled material together with the dispensing pipe 48, as this prevents unwanted contact of the beverage with the dispensing device. The use of the valve 60 therefore provides the advantage that it can be closed before removal of the stub pipe 48, in particular before it is withdrawn, which prevents undesirable substances from settling in the stub device. In the device of the present invention, the beverage is passed through a removable dispensing duct 48, and therefore the beverage does not come into contact with the dispensing device, saving on time and cleaning costs while avoiding the need for environmentally harmless chemicals. A further advantage of the device according to the present invention, in which the tapping pipe is cooled, is that the beverage can remain stationary in the conduit for a long time without deteriorating in terms of consumption. Finally, by preventing the dispensing device from contacting the beverage, the wear of the dispensing device is reduced.

The present invention is in no way limited to the exemplary embodiments shown in the description and the accompanying drawings. It is possible to provide a variety of alternative embodiments within the scope of the invention as defined in the claims.

By way of example, in the embodiment described above, the stub tube 48 has an elastic structure over its entire length, but in another embodiment, the entire stub tube 48 may be rigid or portions thereof may be rigid, i.e. for example, when the conduit is routed in the dispenser rack 8 permanently and may be significantly longer in length so that the refrigerator or at least the container can be placed at a greater distance, for example, in a cellar. Coolants may be omitted and use is solely due to the possibility of introducing the stub pipe, which is particularly important from a hygiene point of view, as explained above. In such an embodiment, the outer first channel may be omitted. Also, the stub stand 8 may have a different structure, such as a divisible stub structure, so that the stub pipe 48 may be placed in a split stub stand and subsequently such a stub stand may be closed around the stub pipe 48. The first end 58 of the stub pipe 48 may be constructed. so that it can be connected to the tap 14 in a different manner using, for example, a quick coupler that can be inserted into the tap, while the valve 60 has a different construction or can be omitted depending on the situation and the tap 14 is designed like a commonly used tap rooster. A plurality of dispensing pipes 48 may be routed in one dispensing rack 8. In the embodiment described above, the guide tube 16 is constructed as a tube that passes through the hollow dispensing rack 8. However, it will be clear that the dispensing rack 8 can also be divided for example by means of a middle wall on two passages extending side by side, the insertion tube 42 being connected directly to one of the two passages for the purpose of introducing the stub pipe 48 into the passage. Then such a partition preferably reaches the proximity of the tap 14 and can be made easily by casting in the tap stand 8. In addition, air can flow directly from the first duct 50 into the interior 22 where it is cooled by mixing with cold air already present in the interior. . Cooled air may also be drawn in directly from the space 84 into the first duct 50 by establishing a corresponding connection therebetween. The dispenser can be attached directly to the top 34 of the refrigerator 4 when such an arrangement is used for recreational or domestic purposes. Of course, the refrigerator 4 of the present invention can be constructed using a variety of different methods with different cooling mechanisms, including a commonly used compressor, evaporator, coolant and pressure vessel. A different number of container containers may be placed in such a refrigerator. Likewise, the controlled air circulation pressure means, which in the described embodiment may be in the form of a fan, may be configured in such a way as to blow air into the channels 50, 52 and thereby generate an increased pressure. However, the use of the vacuum chamber 36 has the advantage that if the tap 14 is not completely airtight, air from the surroundings will be sucked in mainly, which is more acceptable to the user than escaping air into the environment. However, air can be blown around the tap, so that an even greater cooling effect can be achieved. It is then preferred that the air is blown in such a way that it does not cause problems for the user, for example downwards. In addition, other cooling devices, such as water or glycol, may be used in such a case that the first and second ducts form a closed circuit into which cooling means are incorporated to cool the medium and wherein the stub line is at least partially fixed.

These alternatives and a number of other comparable alternatives will be understood as being within the scope of the present invention, which is defined in the appended claims.
